Abstract

processo de combustão distribuídos e queimador. durante a fase de injeção de aquecimento, de um jato de combustível e oxidante (oxidante combustível ou oxidante envolvendo os circularmente cercavam combustível) a partir de um bico de combustível-oxidante é queimado em um espaço de combustão. durante a transição da fase de aquecimento para uma fase de combustão distribuída, uma quantidade de uma porção secundária, quer do combustível ou oxidante é injetado como um jato para dentro do espaço de combustão, enquanto a parte principal desse mesmo reagente a partir do bico de combustível-oxidante é diminuído. em algum momento durante a fase de transição, um jato de fluido de acionamento é injetado em um ângulo para o jato de reagentes a partir do bico de combustível-oxidante e/ou na direção do jato da parte secundária do reagente. o jato de porções primárias de reagentes e/ou porção do reagente secundário é causado para ser dobrado/desviada para o outro dos dois jatos. o estadiamento da porção secundária do reagente é aumentado até um grau desejado de e stadiamento e início de uma fase de combustão distribuída são alcançados.distributed combustion process and burner. During the heating injection phase, a fuel jet and oxidant (fuel oxidant or oxidizer surrounding the circularly surrounded fuel) from a fuel-oxidant nozzle is burned in a combustion space. During the transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space, while the main part of that same reagent from the nozzle oxidizing fuel is decreased. At some point during the transition phase, a jet of drive fluid is injected at an angle to the reagent jet from the oxidizer fuel nozzle and / or toward the jet of the secondary reagent portion. jetting of primary reagent portions and / or secondary reagent portion is caused to be folded / diverted to the other of the two jets. staging of the secondary portion of the reagent is increased until a desired degree of staging and initiation of a distributed combustion phase is achieved.
